Need help with the hardest part in SPLINTER CELL :(

[adzmullz1]

When you have to chase that guard who is going to try and stop feirong killing himself , he goes up the elevator (i have got this far) , but then , he goes through another door on the next floor . does anyone know WHAT THE PASS CODE IS ON THIS DOOR ? . i have tried many a time (about 400) and i just can't figure it out . PLEASE HELP.

you are supposed to use your thermal vision for all these pass codes so you can see the "heat signatures". Follow him as close as possible, so when he's done, the heat from the pad will still be there. When you look at the pad, the last numbers that he punched in will be the most green. The numbers that are almost purple are the ones he punched first. You should be able to figure out the rest. good luck.
